HOBART, Australia, July 27, 2026 /PRNewswire/ — A randomised, double-blind, placebo-
controlled clinical trial evaluated the effects of fucoidan, a naturally occurring
compound found in brown seaweed, on men with BPH (prostate enlargement).

Undaria pinnatifida seaweed – the source of Marinova’s high purity fucoidan compounds.

BPH is a common health issue for men across the globe. Worldwide estimates place
prevalence at 50-60% of men in their 60s, increasing to 90% of men in their 80s.
While it is typically not life-threatening, urinary symptoms – including difficulty
passing urine, a weak stream and an increase in the frequency of urination – often
result in a significant reduction in quality-of-life.

Speaking of the rationale behind the study, lead researcher Dr Barbara Wimmer said,"
To date, very few natural compounds have been clinically studied and shown to support
prostate health effectively. The documented bioactivities of fucoidan led us to 
embark on this groundbreaking trial."

In the 90-day study overseen by clinicians, 88 men aged between 45 and 80 years 
with moderate BPH received either a daily fucoidan supplement or a placebo.

**Key findings**
Compared to the placebo, participants taking the high purity fucoidan
supplement showed:

 ◦ Clinically significant improvements in overall BPH symptoms
 ◦ A more than nine-fold improvement in voiding symptoms (encompassing the symptoms
   of emptying, intermittency, weak stream and straining)
 ◦ A two-fold improvement in storage symptoms (encompassing the symptoms of frequency,
   urgency and nocturia)
 ◦ A significant improvement in quality-of-life due to urinary symptoms

The study utilised the widely recognised International Prostate Symptom Score (IPSS)
to assess changes in BPH symptoms.

Dr Wimmer explained, "Importantly, the trial results were clinically significant
and the fucoidan was shown to be safe throughout the study period. We expect these
findings will result in the commercialisation of high purity fucoidan to help relieve
the symptoms of benign prostatic hyperplasia."

The study was published in the journal [_Research and Reports in Urology_.](https://www.dovepress.com/articles.php?article_id=117409)
